"The Plagued Paladin" scenario

Okay, so here is a scenario I thought up recently. Its much like normal zombies. buuutttttttt...

Depending on how many people are present. Lets sayyyyy 10 people.

2 people are plague zombies, then 7 people are commoners and fighters, and 1 person is the paladin.

They are positioned at opposite sides of the field.

All commoners and fighters have weapons, the two plague zombies are allowed one blue weapon each, and the paladin has one of any weapon and it is a black.

Plague zombies work like normal zombies. They kill you, and in 15 seconds you are now a zombie. The difference is that if a plague zombie touches your skin, in 15 seconds you are a zombie. Even if you kill the zombie that touched you.

The only person immune to the plague effect is the paladin. But a paladin can still be killed in combat.If a paladin kills a zombie, they are to walk off the field and spectate. The only way to truly kill a zombie is if the paladin kills them. Otherwise they resurrect after 20 seconds.

Basicaly the object of the scenario is for the paladin to rescue as many people from becoming zombies, or eliminating all the zombies on the field.
